An attack on the certificateless signature scheme from EUC Workshops 2006

Je Hong Park

Abstract

In this paper, we will show that the certificateless signature scheme recently proposed by Yap, Heng and Goi at EUC Workshops 2006 is insecure against a key replacement attack. Our attack shows that anyone who replaces a signer's public key can forge valid signatures for that signer without knowledge of the signer's private key.
